Point attack insert for rotatable cutting tool
An improved rotating cutting bit used in a road resurfacing machine, wherein the cutting bit includes a metal shank and having a forward end, and wherein the forward end includes a bore or recess that is adapted to fixedly receive at least a portion of a point attack insert. The improvement comprises a head section; an axially aligned transitional intermediate section contiguous with the head section having a first diameter, d, and a sectional height, H1; and an axially aligned base section adjacent to the intermediate section having a second diameter, D; wherein d:H1 is greater than 1.0, the ratio of d:D is from 0.62 to 0.68, wherein the point attack insert has an overall height H and the ratio of H:D is less than 0.93.
